PHP Assumptions is the result of a proof of concept inspired by the "From assumptions to assertions" blog post. It's a static code analysis tool doing checks for weak assumptions.

This is an example of an assumption:

if ($user !== null) {

Running bin/phpa on this file would yield the following output:

| file        | line | message               |
| example.php | 3    | if ($user !== null) { |

1 out of 1 boolean expressions are assumptions (100%)

This is an example of an assertion:

if ($user instanceof User) {
